From: Judy Hsiao <judyhsiao@xxxxxxxxxxxx>

[ Upstream commit f0c8d7468af0001b80b0c86802ee28063f800987 ]

1. Uses regmap_read_poll_timeout_atomic to poll I2S_CLR as it is called
within a spin lock.

2. Fixes the typo of break condition in regmap_read_poll_timeout_atomic.

Fixes: fbb0ec656ee5 ("ASoC: rockchip: i2s: use regmap_read_poll_timeout to poll I2S_CLR")
